Python closing file

I need to close file, but I can’t do that, because I use csv.writer, how can I close file? python

def open_spider(self, spider):
    time = dt.now().strftime(TIME_FORMAT)
    file_path = self.results_dir / FILE_NAME.format(time)
    self.file = csv.writer(open(file_path, 'w'))
    self.file.writerow(['Статус', 'Количество'])

>Solution :

Instead of manually closing the file, it is a good practice to wrap the function under with.

def open_spider(self, spider):
    time = dt.now().strftime(TIME_FORMAT)
    file_path = self.results_dir / FILE_NAME.format(time)
    with open(file_path, 'w') as file:
        self.file = csv.writer(file)
        self.file.writerow(['Статус', 'Количество'])
